GEORGE PARSONS, OF WINNEBAGO, ILLINOIS.

VALVE.

Specification of Letters Patent.

To all whom it may concern:

Be it lmown that I, GEORGE PARSONS, a citizen of the United States, residing at Winnebago, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Valves, of which the following is a specification.

This invention relates Vto valves of the type having a plurality of inlets or outlets, the embodiment herein shown being intended for use with gas arc lamps or other gas lamps having a plurality of burners, whereby the burners may be separately controlled.

One of the objects of the invention is to provide a means for holding the movable v alve member in its various operative posltions.

Another object is to provide means for moving the valve member into its closed p0- sition.

A further object is to provide means for rendering said holding means inoperative to permit the valve member to close.

The invention also relates to other features of improvement in valves, as will be more fully understood from the following description.

lIn the accompanying drawings, Figure l is a vertical central section through a valve embodying the features of my invention, the parts being shown in their closed positions. Fig. 2 1s a similar view but showing the valve fully opened. Fig. 3 is a detail view of the upper end of the movable valve member. Fig. 4 is a section on line 4 4 of Figs. 5 and 6 are sections on line 5 5 and 6 6, respectively, of Fig. 2.

The embodiment which I have herein shown by way of example comprises a body 1 having a nipple 2 at its upper side adapted to be attached to a gas supply pipe, and a plurality of laterally extending nipples 3 arranged for attachment to suitable pipes, not shown, leading to the respective burners of the lamp. The present embodiment is intended for use with a four-burner lamp and therefore has four nipples 3. Extending centrally through the body, and communicating with thenipple 2, is a vertical opening 4 in which is slidably mounted the movable valve member 5. A plurality of ports 6 connect the respective nipples 3 with the central opening 4, said ports being arranged to be opened and closed by the valve member 5.

7 is a chamber in the upper part of the body 1, said chamber being in communication at all times with the nipple 2. A plurality of small pipes 8 (only one of which is herein shown) are fitted in openings 9 in the body 1, and serve to conduct gas from the chamber 7 to the small pilot lights of the lamps. As is commonly understood, these pilot lights are left burning all the time. The iiow of gas through the pipes 8 may be regulated by means of set screws 10 seated in the body 1 and having their ends arranged to enter the openings 9.

' The lower end 1 oft-he body 1 is somewhat reduced in size and has slots l1 extending longitudinally thereof at opposite sides. Said lower end may be termed an extension of the body 1. A spring detent 12 secured at its upper end to the body 1 by means of a screw 13 is arranged to lie in one of the slots 11, the lower end 14 of said detent being adapted to engage in any one of a series of notches 15 in the valve member to hold the valve member in its various operative positions.

Surrounding the extension 1a of the body 1 is a coiled tension spring 16 having its upper end secured to lugs 17 on the body, the lower end of said spring being attached to the lower end of the valve member 5 in any suitable way, as by passing the bottom coil of the spring through a lug 1S on the valve member 5, the end of said coil being bent to provide a loop 19 for convenience 1n attaching a chain (not shown) for operating the valve member 5. As will be observed, the spring 16 tends at all times to move the valve member 5 into position 'to close all of the ports 6.'

In the upper end of the valve member 5 is a notch or lerf 20, the bottom wall' of which is inclined, as clearly shown in Figs. 1 and 3. When the valve member 5 is drawn downwardly so that the detent 12 engages in the notch 15a in the valve member, the nipple 3 at the right-hand side (see Figs. 1 and 2) will be placed in communication with the supply nipple 2 through 4the port 6 and the notch 20. It should be noted that in this position of the valve member, the portion of Patented Dec. 12, 1911. Application filed July 5, 1910. Serial No. 570,403.

the notch 20 at the left side of said member is not deep enough to register with thelefthand port 6, therefore gas is supplied to only one burner. In the next lower position of the valve member, in which the detent 12 engages in the notch 15b, the notch 20 in the valve member is brought into register with the left-hand port 6, so that the second burner is lighted. When the valve member is moved into its lowermost operative position (shown in Fig. 2) the two remaining ports are uncovered to supply gas to the remaining burners of the lamp.

`I have provided a means for holding the detent 12 out of engagement with the valve member 5 when it is desired to close the valve, said means comprising a ring 21 surrounding said valve member and lying in a recess 22 in the lower end of the body portion 1a. Said ring 21 is normally supported in position by a shoulder 12a upon the detent 12.

23 and 24 are pins or other suitable projections carried by the valve member 5.

Assuming the parts to be in the position shown in Fig. 2, and it is desired to close the valve, the member 5 is pulled downwardly a short distance, the pin 23 engaging the ring 21 and carrying said ring downwardly past the shoulder 12a on the detent 12, thus moving said detent out of engagement with the notch 15c in the valve member. The spring 16 will now move the valve member upwardly to close the valve. Near the end of such upward movement, the pin 24 on the valve member 5 will engage the ring 21 and carry said ring upwardly into its normal position to permit the detent- 12 to again engage the valve member, as seen in Fig. 1. The lower portion of the detent 12 may be slotted as at 14a to permit the pin 24 to pass the shoulder 12EL and projection 14; on said detent.
